Exam #2 questions with answers |\ |\ |\ |\
4 phases of respiration - CORRECT ANSWERS ✔✔1. Pulmonary
|\ |\ |\ |\ |\ |\ |\ |\ |\
ventilation
2. External gas exchange
|\ |\ |\
3. Gas transport in the blood
|\ |\ |\ |\ |\
4. Internal gas exchange
|\ |\ |\
Respiration - CORRECT ANSWERS ✔✔Inhalation and exhalation of
|\ |\ |\ |\ |\ |\ |\ |\
air. The process by which O2 is obtained from the environment
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
and delivered to the cells.
|\ |\ |\ |\
Structures of the Respiratory System - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\
✔✔Nasal cavity,Pharynx, Larynx, Trachea, Bronchi, Alveoli
|\ |\ |\ |\ |\
pulmonary ventilation - CORRECT ANSWERS ✔✔movement of air
|\ |\ |\ |\ |\ |\ |\ |\
into and out of the lungs/exchange of air between the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
atmosphere and the air sacs (Alveoli) |\ |\ |\ |\ |\
External gas exchange - CORRECT ANSWERS ✔✔occurs in the
|\ |\ |\ |\ |\ |\ |\ |\ |\
lungs as oxygen diffuses from the air sacs into the blood and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
carbon dioxide diffuses out of the blood to be eliminated
|\ |\ |\ |\ |\ |\ |\ |\ |\
Gas transport in the blood - CORRECT ANSWERS ✔✔The
|\ |\ |\ |\ |\ |\ |\ |\ |\
circulating blood carries gases between the lungs and the
|\ |\ |\ |\ |\ |\ |\ |\ |\
, tissues, supplying oxygen to the cells and bringing back carbon
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
dioxide.
Internal gas exchange - CORRECT ANSWERS ✔✔occurs in the
|\ |\ |\ |\ |\ |\ |\ |\ |\
tissues as oxygen diffuses from the blood to the cells, whereas
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
carbon dioxide travels from the cells into the blood
|\ |\ |\ |\ |\ |\ |\ |\
compliance - CORRECT ANSWERS ✔✔The ease with which one |\ |\ |\ |\ |\ |\ |\ |\ |\
can expand the lungs and thorax
|\ |\ |\ |\ |\
Diffusion - CORRECT ANSWERS ✔✔Movement of molecules from
|\ |\ |\ |\ |\ |\ |\ |\
an area of higher concentration to an area of lower
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
concentration/concentration gradient |\
two phases of ventilation - CORRECT ANSWERS ✔✔inhalation and
|\ |\ |\ |\ |\ |\ |\ |\
exhalation
|\
Surfactant - CORRECT ANSWERS ✔✔chemical produced in the
|\ |\ |\ |\ |\ |\ |\ |\
lungs to maintain the surface tension of the alveoli and keep
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
them from collapsing|\ |\
Difference between the left and right bronchi - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔right bronchi is larger and extends more vertically.
|\ |\ |\ |\ |\ |\ |\ |\ |\
(this is where a foreign object will most likely lodge)
|\ |\ |\ |\ |\ |\ |\ |\ |\
hypoventilation - CORRECT ANSWERS ✔✔causes increased |\ |\ |\ |\ |\
CO2/H+ in blood & acidosis
|\ |\ |\ |\ |\
